[iOS Game] Settlers of Catan $4.49 (from $7.49); Rivals for Catan $1.49 (from $6.00)

Price drop of all USM's games.
Game may still seem very expensive to most people, so it may not be for everyone, but if you're not aware Catan is a classic board game and the iOS game has been really great. Current average is 4.5/5 stars on App Store.

Note: iPad users have to get the separate Catan HD app

App description from the developers:

True to the original game, you can compete with up to four players for the most settlements, the longest roads and the largest army. You can trade with each other and claim the precious land with all its resources. The game allows you to challenge other Catan fans online via cross-platform multiplayer to prove your strategy skills or play against the AI.

The popular Catan expansions "Seafarers", "Cities and Knights" and two new special scenarios are available as In-App purchases.

Never played Rivals so can't vouch for its entertainment value.
